THREAD AND PROCESS OF FORMING SAME.

ess of forming same and has for its object to provide a thread simple in construction,

. economical of production and efficient for use in textile fabric.

To these ends my improvements include a plurality of steps which may be practised in part or as a whole and in various sequences to produce thread adapted for a variety of uses.

In Figure 1 of the drawings accompanying this specification I have illustrated in diagrammatic side elevation a mechanism suitable for the practise of a portion of the steps of my improvements. Fig. 2 is a diagrammatic elevation of means for twisting stripsmade in accordance with my improvements, into threads. Figs. 3, 4 and 5 are perspective views illustrating several modifications of the final step in my improvements.

In Fig. 1, 2 represents the dofl'er cylinder of a carding machine of some well-known construction; 3 is the dofler comb and 4, 4, 5, 5, 6, 6 are a plurality of pairs ofrollers. Rolls 4, 4 are rotated in the direction of their arrows respectively, at a surface speed about the same as the surface speed of cylinder 2. Rolls 5, 5 are rotated at a speed somewhat in excess of that of rolls 4, 4 and rolls 6, 6 are rotated somewhat faster than rolls 5, 5. 1

Fiber, such as cotton, flax or other suitable kind is delivered from cylinder 2 by doffer comb 3 to rolls 4, 4, either directly or over a guide as 12, and thence bet-ween rolls 5, 5 and 6, 6. The web of fiber is this increased in speed from pair to 'pair of said rolls, and thereby drawn thinner and longer and the fibers thereof laid lengthwise and into approximate parallelism. From rolls 6, 6 the fiber web passes onto carrier belt 7 whichis mounted on convenient rollers 8, 9 rotated at about the surface speed of said rolls 6, 6. Adjacent said belt 7 and preferably adjacent to rolls 6, 6 is a spraying pipe 10 through suitable apertures in which a spray of sizing liquor is delivered onto the suitable receptacles not shown.

fibrous web. Adjacent said belt 7 and preferably distributed lengthwise thereof I may provide drying means comprising steam pipes 11, 11 or said pipes may be perforated and an air blast be used for drying the sized Web. By applying sufiicicnt sizing liquor from pipe 10 the fiber web may be sized throughout its thickness, from face to face. Or if only enough sizing is applied at 10 to size the top surface of said web I may turn over the web by passing it onto another belt 13 and from pipe 16 size the other face. Said belt 13 may be supported on and actuated from rollers 14, 15 and drying means 17, may be supplied adjacent the upper run of said belt 13. From sizing and drying belt 13 I deliver the web to slitting means as cutting rolls 18, 19'by which said Web is divided lengthwise into strips. I preferably employ traveling apron or belt 20 mounted on rolls 21, 22 for deliveringthe web from belt 13 to rolls 18, 19. From said cutting rolls the web strips may be wound onto spools as 23, 24 or passed into Between cutting rolls 18, 19 and spools 23, 24 I preferably employ feed rolls 25, 26. After sizing the web on both faces as described I may split or divide the resultant strips into two layers, winding the top sized portions onto spools 23, 23 and the bottom sized portions onto spools 24, 24. To assist said splitting I preferably employ dividing blade 27. By this procedure I produce a strip of fibrous Web having one relatively smooth sized face and one relatively fleecy or free fibrous unsized face. If it is desired to size the web only once I lead said web from belt 7 directly upward to between cutting rolls 18, 19. j

The succeeding steps in my improved process are directed to forming the web strips into threads. This may be done by simply twist-ingany one of the several varieties of strips described, directed into a thread, by any of several well known means, such for instance as that shown in Fig. 2. However, I preferably form threads by separately twisting the strip portions WllICh have one smooth face and one fieecy face,

with the smooth face turned inwardly and without prior folding, (Fig. 4) so as to present an entire exterior of fleece; or two strip portions may be laid smooth face to smooth face and then twisted into one 5 thread having the fleece face entirely surrounding the thread (Fig. 5). For twisting the form of thread shown in Fig. 3 the strip from a roll as 24-, Fig. 2, may through plaiter 40 and thence between rolls 30, 31, through guide 32 to twister T, comprising the well-known flier 33, spindle 34,

bobbin 35, whirl 36 for driving said bobbin and whirl 37 for driving said flier. For twisting the form of thread shown in Fig. 4 plaiter 40 may be omitted. For twisting the form of thread shown in Fig. 5, two strips may be led smooth face to smooth face from rolls 23, 23 to between rolls 30, 31 and the rest of the process may be carried on as be led already described. Again if desired any of,

I claim I 1. The process of forming athread including in combination, the-formation of a web of fibrous material, sizing said web on its top face and bottom face, dividing the web sized portions of said strips from the bottom sized portions respectively, thus producing strip portions each having one sized face and one fieecy face and twisting said strip portions into threads.

2. The process of formingathread includ:

lengthwise into strips, dividing the top ing in combination, the formation of a web of fibrous material, sizing said web on its top face and bottom face, dividing said web lengthwise into strips, dividing the top sized portions of said strips from the bottom sized portions respectively, thus producing strip portions having onesized face and one fleecy face and twisting said strip portions with their sized faces inside and their fleecy faces entirely surrounding the thread.
